Ostrander MM is a different beast from the usual MM, and would make for the best fight against Thor imo..
He was using his shape shifting powers to absorb metals and armor up, change his size, create shields that could block Apokolips swords that could normally cut him, even if he's intangible, create a third arm to increase his offensive power.. He even made stabbing weapons that went clean through Etrigan the Demons chest, and Etrigan is pretty durable.

Nah, he'd have loads of trouble, the Spectre was nailed by Batman, so his powers are highly irregular. Thor's mind can be as tricky as the Hulk's when he's determined and pissed, so TP is not a for sure victory. Thor on the other hand can truly make him disappear into another dimension.I don't think that Thor would crush the life out of him, or steam roll MM, but I do think that he would win convincingly enough to give him a 6-7/10 victory.
MM has rendered Joker's brain sane in Morrison's JLA and his brain was probably a lot more complex than Thor's. Thor has been taken down by tp attacks before.
